HUB-BEARING.

Application filed May 3, 1920.

To all whom it may concern Be it known that l, TRUMAN l3. FUNK, acitizen of the United States, residing at ll/loline, in the county ofRock Island and State of Illinois, have invented certain new and usefulImprovements in Hubddearings of which the following is a specification.

The present invention has to do with certain improvements in bearings.The invention has reference particularly to the construction andarrangement of parts which are lubricated by means of oil or lubricantcirculated under pressure. The features of the invention are very welladapted for use in bearings for automobile fans and thelike, although itwill resently appear that the features of the invention also be used inother locations and for lubrication of other bearings. Neverthe less,inasmuch as the features of the in vention are especially well adaptedfor lubrication of automobile tan bearings, I have illustrated theinvention and will describe the same as being applied to this particulartype of bearing.

One of the objects of the present invention is to provide a bearing ofvery simple construction and one which can be made cheaply and from aminimum number of parts.

Another object of the invention is to provide a bearing for fans ,andthe like, which will be self-contained, and of which the parts are soformed that they can be very easily cast and put through the variousmanufacturing operations.

Other objects and uses of the invention will appear from a detaileddescription of the same which consists in the features o'l constructionand combinations of parts hereinafter described and claimed.

F 8 shows a section taken on the line 8-8 of Fig. 7, looking in thedirection of the arrows; and

Fig. 9 shows a detailed section taken on the line 9-9 of Fig.5, lookingin the direction of the arrows.

I will first describe the construction shown in detail in 1 to atinclusive.

In this case, there is provided a stud or pin 10, the end portion 01"which is lined to a stationary part such asthe engine trains, and thebody portion of which serves as a shaft or support for the hearing. Thebody portion of the bearing comprises an inner sleeve 12 which seatsdirectly upon the pin 1G. and an outer shell member 13 which encirclesbut is spaced away trorn said sleeve. The shell member 13 tapers fromits inner end 14 to its outer peripheral portion 15, the inner end 14-being drawn inwardly and closely encircling the stud or pin 10.

A series of separated lugs 16 are provided on the inner end of thesleeve 12 (only one oi said lugs appearing in F 1). These lugs serve to:lurther support the inner end oi the shell 13 while permitting oil orlubricant to circulate ireely past the lugs. The outer end of the sleeve12 is flared outward to provide a flange 17'; and the out-er end 15 ofthe shell 13 seats against the periphery of said flange to which it maybe socured in any suitable manner. This arrangenient serves to inclosean oil space or chamber 18 between the sleeve and shell, and a plug 19may be used to close an opening through which said chamber may be filledfrom time to time. A pulley flange 20 may be formed integral with theshell 13, as clearly evident from Fig. 1.

in the outer face ot the flange portion 17 may be provided a circularrecess 21 concentric with the stud or pin 10, and a hole number ofparts.

22 is formed at the center of said recess to receive the end portion ofsaid stud or pin. Another circular recess 23 is formed in the outer faceof the flange 17 and merges segmentally with the recess 21. An oilperforation 261- extends through the flan e from the recess 23 to theinner or back face of the flange; and a slotted recess 25 extendsbetween the circular recesses 21 and 23 at the point where the teeth ofgears operating or located in said recesses-will mesh.

On the end of the stud or pin 10, or f rmed integrally therewith, asdesired, is a gear 26, the'teeth of which closely engage the circularwall of the recess. A pinion 27 is located within the recess 23 and itsteeth closely en 'age the wall of said recess, and also mesh with theteeth of the gear 26. The pinion 27 is mounted on a stud 28 in theflange 17. The arrangement is such that oil drawn through theperforation 2 1 will be carried around by the teeth of the pinion 27 tothe point where the teeth of the pinion and gear come together, and willthen be forced down through the slotted passage 25 and against the studor pin 10. Said oil will then be compelled to travel along the stud orpin and lubricate the same. It will finally work its way through and bedelivered adjacent the inner end 14c of the shell. A fan plate 29'seatsover and is secured to the flange 17 and carries the fan blades 30, ifthe same be used. This plate 29 also closely engages the gear and pinionaforesaid so as to insure the flow of oil in the manner just explained.

It will be observed from an examination of this construction that itmakes use of parts which may be very easily cast in molds of very simpleforms, and from a minimum It will also be observed that thisconstruction involves the use of a sleeve seated directly upon the studor pin,

I and having its outer end flanged in conjunction with an encirclingshell which engages the peripheral portion of said flange.

Referring now to the construction shown in Figs. 5 to 9 inclusive, thesame is a modilication of that just described in detail. In this presentcase, the sleeve 12 has its inner end 31 carried beyond the inner end 14of the shell 13, so that said inner end 14 is directly supported by thesleeve 12. Furthermore, a groove 32 is provided encircling the innerface of the sleeve 12 adjacent 1 to the inner end 31 thereof so as tocollect the oil flowing along the stud or pin and deliver the same intothe space or chamber 18 through the medium of a series of openings 33.It is also observed that on the inner face of the shell 13 adjacent toits outer end 15 ther is provided an encircling groove 34 for thepurpose of insuring a perfect seal between said outer end 15 and theflanged portion 17. It is also observed that the lugs 16 of thearrangement shown in Figs. 1, 2, 3, and 1, are dispensed with in thepresent case, since the inner end of the shell is directly supported bythe inner end of the sleeve.

While I have herein shown and described certain embodiments of mypresent invention, still I do not limit myself to the said embodimentsexcept as may do so in the claims.

I claim: 1. A pressure lubricated bearing comprising, in combination, astationary stud, a sleeve journaled thereon, an outshzndhig flange atthe outer end of said sleeve, a concentric shell surrounding said sleeveand spaced away therefrom to provide an annular oil space, the inner endof the shell being supported by the inner end of the sleeve, and theouter end of the shell hein in engagement with the peripheral portion ofthe sleeve flange to inclosc the oil space aforesaid, there being acircular recess in the outer face of the sleeve flange concentric withrespect to the stud, a gear located in said recess and rigid withrespect to the stud, there being another circular recess in the outerface of the sleeve flange and in peripheral communication with the firstmentioned recess, a pinion rotatably mounted in the second mentionedrecess. a cover plate extending over the gear and pinion and saidrecesses and serving, in conjuuctimi with the sleeve flange, to incloscsaid rccesses, there being an oil passage extending through the sleeveflange and establishing communication betweeu thc oil space and the pathof travel of the pinion teeth. and there being another recessestablishing communication between the point of ennies n ment of theteeth of the pinion and ge and the end of the stud, suhstautiall.described.
